If you look closely at the pics above of both the stock Trick Flow and Victor 440 intakes, you'll see that is how both brands cast the floors of their intakes. Not really a turtle IMO, but maybe something to reduce fuel pudding. I think of turtles as being used more for tuning fuel distribution.

Thanks Andy and Brad. After looking at the "before" pics again, I see what you're talking about Brad. Didn't notice it before.

Ok, it's 9 months after I started this. Has anyone seen a test that uses both intakes on the same engine?

5-years later there should be some answers now to all the questions asked in this thread.

So, 5 years later, the answers are:
1. PorkyPig is an a-hole
2. BradH is an idiot
3. Trick Flow is better out of the box
4. Both intakes are comparable if fully ported

Tony Bischoff did an Engine Masters Mopar entry some years ago where I saw pics of the engine using both intakes at different times. I believe he went with the Edelbrock because Trick Flow wasn't paying sponsorship bonus for their intake, but Edelbrock was.

Well I would have thought more would have commented on this thread. For what it's worth I redid the plenum on my Victor and added a homemade pyramid on the bottom.

Intake Plenum

Here's what I made and installed on the floor. The center point of the pyramid is a piece of thread all, and It's epoxied and bolted through the bottom of the intake floor with a nut on the underside.

Then using a 1" Jomar 4-hole Power Cone spacer on the top.

Did it show up on the ET slip or engine dyno?

The one mod to my old Victor intake which made an improvement was modifying the radius at the tops of the runner entries per the pics I posted above

Not sure why, maybe it's a firing order thing ? ie 5/7 and it also covers a 4/7 swap (4 then 2) . I know some have found better fuel distribution and a little more power extending the runner on the adjacent firing cylinders. Theory is the later opening cylinder "steals" some of the charge due to the difference in vacuum between cylinders
